Steps:

For some reason, if you get a message like following:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Someone could be eavesdropping on you right now (man-in-the-middle attack)!

It is also possible that a host key has just been changed.

The fingerprint for the ECDSA key sent by the remote host is

SHA256:iudbciuwbciubwi/TFutvavUVUY/76THBSJHB7Shdb.

Please contact your system administrator.

Add correct host key in /Users/user/.ssh/known_hosts to get rid of this message.

Offending ECDSA key in /Users/user/.ssh/known_hosts:2

ECDSA host key for 192.168.0.XXX has changed and you have requested strict checking.

Host key verification failed.

then do this on your terminal:

ssh-keygen -R 192.168.0.XXX
